Mixing It Up

The GM is free to add any number
of twists. For instance:
• Start with a hierarchy of realities,
as explained under Worlds Within
Worlds, but place parallel worlds on
some tiers of the hierarchy.
• Start with worlds that abut on
worlds, as described for Parallel
Worlds, but make certain “worlds”
fully realized hierarchies of dimen-
sions instead of simple physical
realities.
• Add any number of distinct phas-
es to some or all of the worlds in the
setting (e.g., each physical reality
might have its own hyperspace and an
ethereal plane).
